Under the Consumer Rights Act 2015, goods should be of satisfactory quality, fit for purpose and as described. If they are faulty, you may be entitled to a repair, replacement, price reduction or refund, depending on the circumstances and how long you have had them. The retailer, rather than the manufacturer, is usually responsible, and you generally have stronger rights within the first 30 days. For online purchases, a separate 14-day cancellation period often applies, although exceptions exist; check GOV.UK or speak to a solicitor regulated by the SRA if your situation is disputed.
